The hardness reading on the cots surface has an impact of
the cots core hardness which is of metal or harder polymer.

Hardness measured on cot will be generally higher than the
designated hardness by 2 3 degree
Softer the cot, higher is the impact of Core hardness as
shown in the fig.
With the reduction in diameter of the cots after repeated
buffing , the impact of core hardness increases (Please refer the below
table )
